Which table shows a negative correlation?

The correct answer is:

The last table.

Explanation:

A negative correlation means that as x increases, y decreases.

In the first table, as x increases, y increases; this is a positive correlation.

In the second table, as x increases, y stays constant. This is not a negative correlation.

In the third table, as x increases, y first decreases, then increases. This is not a negative correlation.

In the last table, as x increases, y decreases; this is a negative correlation.
